(US GOVERNMENT) Immigration and Naturalization Service: former agency of the US government responsible for the enforcement of immigration law, and the processing of visa/permit requests. The INS and its successor (see below) are justly famous for treating millions of hardworking, intelligent, and creative people with the most demeaning, barbaric sort of bureaucratic cruelty imaginable.

Prior to its dissolution in 2003, the INS was part of the Department of Justice. The CIS and ICE are both part of the DHS.

Because of its extraordinary power over the lives of millions of US nationals and residents, the Immigration and Naturalization Service gained lasting notoriety. Seven years after it was superseded by the CIS, most people associated visa regulations with the INS.

"Brother from Another Planet" was a brilliant parody of INS agent behavior.
